#3 is a triangular pyramid because triangular pyramids have 4 triangular faces.
#4 is a cube because there are 6 square faces.
#5 is a triangular prism. It has 2 triangular faces and 3 rectangular faces.
#6 is a rectangular prism. It has 2 square faces and 4 rectangular faces.

Answer:
117 degrees
Step-by-step explanation:
So we already know that one angle is 38 degrees, so we have that one. The angle, 101 is exterior, and we have to subtract 180 from that to get the interior angle. We get a difference of 79. Since the sum of a triangle's interior angles are 180, we have to add 38+79 to get 117. Then, we have to subtract it from 180 to get the value of the interior angle as 63 degrees. Because x is on the outside, we have to again subtract 63 from 180 to get the missing value of x as 117.
Answer:
Todd's Z-score is - 0.27
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<u><em>Step(i)</em></u>:-
Given data A test is normally distributed with a mean of 70 and a standard deviation of 10.
<em>Mean of the population 'μ' = 70 </em>
<em>Standard deviation of the Population ' σ ' = 10</em>
<em>let 'x' be the random variable in normally distributed</em>
<u><em>Step(ii)</em></u>:-
<em>Given raw score 'x' = 55</em>
Todd's Z-score
Z = -0.27
<u><em>Final answer</em></u>:-
<em>Todd's Z-score is - 0.27 </em>
